IMPRO'VED EDGE-PLANE. w The Schedule' referred 'to in these Letters Patent and making part of the same.

To all whom it may conce/rn Be it known that I, CHARLES I. BIGELOW, of Clinton, in the county of Worcester, and State of Massachusetts, have invented a new and valuable Improvement in Edge-Planes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference-being hadto the annexed diawin gs, making a part of this speciiicatiomand to the'letters and figures of reference marked thereon.

My invention relat use; and

It consists in providing more e'icient means than have heretoforebeen 4devised for paring, or 'trimming the edges of the soles of boots and shoes.

Letter A represents the handle of the edge-plane, se. cured to the body B by means of a shank, D.

-Letter C represents an ear-shaped throat, which throws out the chips of leather on the side opposite to the boot or sho Letter E represents the knife-blade arc of a circle, of uniform thickness, turned up at the sides.

On the side of the knife nex a raised ridge, or lip, upper edge of the sol describing thewith the edges t to the boot or shoe, is a, whose oice is to pare off the e.A In its operation of paring, it g the upperleather by shield b, as shown in iig. 2 of drawings.

AAt'the same time, the lip a cuts a groove on the upper edge of the sole, without'any danger of c'u'ttiug the upper leather, being protected by shield b.'

When the knife needs sharpening, it is easily removed by means of set-screw o, and when worn out, lcan be replaced by another.-
